Introduction
Stratix II devices are available in space-saving FineLine BGA® packages
(see Tables 1–2 and 1–3).

Notes to Table 1–2:
(1) All I/O pin counts include eight dedicated clock input pins (clk1p, clk1n, clk3p, clk3n, clk9p, clk9n,
clk11p, and clk11n) that can be used for data inputs.
(2) The Quartus II software I/O pin counts include one additional pin, PLL_ENA, which is not available as general-
purpose I/O pins. The PLL_ENApin can only be used to enable the PLLs within the device.
(3) The I/O pin counts for the EP2S60, EP2S90, EP2S130, and EP2S180 devices in the 1020-pin and 1508-pin packages
include eight dedicated fast PLL clock inputs (FPLL7CLKp/n, FPLL8CLKp/n, FPLL9CLKp/n, and
FPLL10CLKp/n) that can be used for data inputs.

All Stratix II devices support vertical migration within the same package
(for example, you can migrate between the EP2S15, EP2S30, and EP2S60
devices in the 672-pin FineLine BGA package). Vertical migration means
that you can migrate to devices whose dedicated pins, configuration pins,
and power pins are the same for a given package across device densities.
To ensure that a board layout supports migratable densities within one
package offering, enable the applicable vertical migration path within the
Quartus II software (Assignments menu > Device > Migration Devices).
